Regions

Chic-Choc Mountains.

The mountains should be back to their wintry selves by Monday. It should be remembered, however, that the height of the snowpack was very low and that the new snow is likely to lie directly on the ground in many places. Natural obstacles (rocks, stumps) will therefore be very close to the surface.

Confidence

Low

Avalanche Summary

No new avalanches have been observed or reported over the last few days.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

The weather over the past two weeks has had the effect of prematurely melting the snowpack in the mountains. In many places, no snow remains.

A significant refreezing crust, capable of supporting the weight of a skier, is present on all aspects and at all altitudes. The snow expected on Sunday night will rest on this crust and may not adhere to it very well.

Weather Summary

Synopsis: A winter storm will affect the region from Sunday evening, bringing heavy accumulations of snow until Tuesday.

Sunday evening and night: Cloudy. Snow sometimes heavy, 20 to 30 cm. Extreme south-easterly wind of 80 to 100 km/h. Low -5.

Monday: Snow. 5 cm. Strong east wind, 50 to 60 km/h. Maximum -3. Freezing level at 200 m.

Tuesday: Snow. 5 to 10 cm. Strong northeast wind, 50 to 70 km/h. Maximum -3. Freezing level at 200 m.

Wednesday: Cloudy. Wind northeast, 20 to 30 km/h. High -2. Freezing level at 500 m.

Terrain and Travel Advice

  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
  • Wind slabs are most reactive during their formation.
  • Be cautious of buried obstacles especially below treeline.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
